Oy. I have what I know would be considered nitpicks about some of the hints and so I am apprehensive about listing them. But the fact that there are so many in one quiz is unusual, and really lowers its overall quality, compared to most quizzes on the site.
It's too bad when all feedback gets lumped in as "nitpicking" -- some definitely would make the quizzes better. Oh well. Looks like the comments have been deleted anyway.
